“It’s a terrible, terrible tragedy honestly and our thoughts and prayers are really with the family right now,” Thompson said.

Thompson could not give specifics on the anesthesiologist and the dentist who performed the surgery, but he says all his staff are trained extensively and have years of experience. They always have a dentist, an anesthesiologist and two other staff members in the room while patients undergo surgery.

Parents are not allowed in the same room during surgery because the room has to be sterile and clean.

“It’s considered a clean room and so parents can’t actually walk back in there with their street clothes on and things like that,” Thompson said.

He also said they always tell parents not to feed their child the night before surgery, as well as the risks associated with the procedures.

The Dental Board of California released the following statement:

“The Dental Board of California is aware of the tragic situation. An investigation is underway so specific details of the case cannot be shared at this time. Consumer protection is the board’s highest concern and we want to extend our deepest sympathy to the family.”
